How to filter a objectlist in javascript by date

Question

I have lightning controller in were I want to filter a list based on a datefield. I tried the following but end up with an empty list:

My list has 2 records:

serverList[0].Startdatum__c = 1-12-2018
serverList[1].Startdatum__c = 30-7-2018

startdate = 02-08-2018


var serverListFilteredbyDate = serverList.filter(function(item) { return item[(serverList[i].Startdatum__c >= startDate)]});   

Answer 1

As written, you're trying to subtract numbers (02-08-2018 = -2024). Instead, you need to make sure you're using Date objects:

startdate = new Date("02-08-2018")

I believe you'll also need to do this for the values in the field as well.

As N.B. commented while I was writing, you use "item" (the variable) to do the filtering. You could actually write it more like this:

startdate = new Date("02-08-2018")
var serverListFilteredbyDate = serverList.filter(item => new Date(item.Startdatum__c) >= startDate);
